"We were angry and said/did things we didn't mean"

"We rushed into this"

"We both agreed to xyz"

and other "we" statements that are bullying and manipulation tactics to erode your sense of self.

When men say this, the "we" should actually be replaced with "I" but he won't admit and take FULL responsibility of his words and actions. So, instead he "we's" it. More than likely whatever the woman said in anger was pent up resentment and a call out of the bullshit and what the man said was mean spirited and has been there from the start.

Don't let him place his responsibility and actions on you.
